I am having excessive heat issues and low humidity issues. I started with a 3X3 grow tent with 400W MH so it was easy to vent out heat and open the tent when the lights were on to be able to get some "intake." However, I have recently expanded my grow area and now use my tent for a veg/clone chamber and use the rest of the room for a flowering room. I added a 600W HPS for flowering. I am having issues in the flowering room as temps are getting up as high as 90deg and humidity as low as 30%. Plants are showing signs of heat stress and also showing a little bit of nute burn because they are using up more water. The room is about 720 sq ft. I feel I have enough equipment to be able to deal with this, but it's not setup right? I have a fan that is too big...it pulls 400 and some CFM, I also have a smaller booster fan that pulls about 240 CFM. Originally I was using the booster for just the tent and the big fan for the rest of the room. But it was pulling out just about all of the humidity...so i added a small humidifier, but it's not able to keep up with amount of heat generated. I also tried an air conditioner to keep it cooler, however, it also pulls all the humidity out. There are no windows in the room, and keeping the door open pulls in dry air. I do have a hole in the wall that vents air out, but I don't know how I should set this up...any help would be appreciated.
